1. The problem statement, all variables and given/known data

a roof that has a rise of 5 meteres for every 14 meters of horizontal run. A girl stands on a scale on the roof and the scale reads 120N . what is the actual weight of the girl? what force tends to slide the girl off of the roof?

2. Relevant equations

tan theta=opp/adj

cos theta=adj/hyp

3. The attempt at a solution

i found the degree first, which is 19.65 degrees, I found this by using tan equation. Then I used this degree to find the weight of the grl, which is 127.39N, used cos equation. Then finally, using the degree again and tan equation, the force sliding the girl off the roof is 42.84N. I just want to know if I have the answer right? Thank you for the help!!!
